acheter une alliance diamant<\/a>, il faut appliquer l\u2019une de ces solutions. <\/p>\nLa m\u00e9thode du papier de verre. Cette m\u00e9thode est l\u2019une des plus simples et des plus ordinaires. Elle consiste \u00e0 mettre \u00e0 rude \u00e9preuve, la solidit\u00e9 du diamant. Il faut dire que le diamant est l\u2019une des pierres les plus dures au monde. Pour diff\u00e9rencier le vrai diamant du faux, il suffit de frotter un morceau de verre contre le diamant. S\u2019il y a des traces sur le diamant, alors ce dernier est un faux.<\/p>\n
L\u2019autre m\u00e9thode de distinction consiste \u00e0 faire un point noir sur un bout de papier blanc. Il faudra alors disposer la base du diamant sur le point dessin\u00e9.Si on aper\u00e7oit un reflet circulaire en m\u00eame temps que le point noir, on en d\u00e9duit que ce diamant est un faux. Si c\u2019est un diamant authentique, le reflet demeure imperceptible. Une autre m\u00e9thode consiste \u00e0 souffler de l\u2019air chaud sur le diamant. Si la bu\u00e9e d\u2019air ne dispara\u00eet pas, alors le diamant est un faux.<\/p>\n
Le diamant est un grand diffuseur de chaleur, et donc ne peut s\u2019embuer. Il y a aussi le test de verre d\u2019eau qui consiste \u00e0 d\u00e9poser le diamant dans un bocal d\u2019eau. Si la pierre plane, alors elle est fausse. Le vrai diamant coule instantan\u00e9ment dans l\u2019eau.<\/p>\n
Les m\u00e9thodes modernes d\u2019identification<\/h2>\n
Il n\u2019existe pas d\u2019astuce qui soit enti\u00e8rement cr\u00e9dible en mati\u00e8re d\u2019authentification de diamant. Le moyen le plus s\u00fbr pour savoir que l\u2019on poss\u00e8de un vrai diamant est le laboratoire. En effet, les laboratoires de gemmologie sont les seuls habilit\u00e9s \u00e0 authentifier de fa\u00e7on incontestable les diamants. Ils \u00e9tablissent \u00e0 cet effet un certificat qui prouve que la pierre concern\u00e9e est un vrai diamant. <\/p>\n
Il existe \u00e9galement des appareils qui sont con\u00e7us pour cela. On les appelle les testeurs de diamant. Ce sont de petits appareils portables contre lesquels on dispose le diamant. D\u00e8s que la pointe du testeur touche le diamant, le r\u00e9sultat s\u2019affiche sur le cadran. Il est important de signaler qu\u2019il existe des diamants artificiels aussi. Ils ont \u00e9t\u00e9 fabriqu\u00e9s par les laboratoires dans les m\u00eames conditions de temp\u00e9rature que les diamants naturels. <\/p>\n
Ils pr\u00e9sentent donc les m\u00eames traits et les m\u00eames caract\u00e9ristiques que les vraies pierres, mais \u00e7a ne veut pas dire qu\u2019ils sont faux. Il faut savoir authentifier les pierres pr\u00e9cieuses pour ne pas arborer de faux diamants. Plusieurs moyens existent pour le faire, il faut choisir le plus adapt\u00e9.<\/p>\n","protected":false},"excerpt":{"rendered":"
